I have a set, and because i like them i keep my eye out for them, but you must know where to shop because I'd say often more and that $50 is pretty good buying if in good condition. Haven't seen them still attached to a butchered frame before though, so who knows what that does to the price.

That one looks a lot more like a DeRosa than his did. The angles and clearances look about right for a higher end early 80s bike, anyhow.

That guy was a laugh, I kinda miss him and his fakenagos owned by football players, sold it for a bazillion dollars on gumtree. Shame he was a spiv and not an honest clearer of garages.

As for that "de rosa", lack of clarity in the photos aside, the rear dropouts and fork crown look good quality and the group looks very neat. And there's no mention of football players so it's probably legit
